About

The Greenland Open Space Pack Burro Races take place in Palmer Lake, Colorado, on September 26, 2027, with two trail distances starting together at 10 a.m.: 8 miles (12.9 km) and 3 miles (4.8 km). The event's name refers to pack burro racing, a discipline associated with Colorado.

At 8 miles, the longer race sits between a 10K and a half marathon and can be prepared with hour-long trail runs and a little hill work. The 3-mile race suits a first trail outing or a family entry. In this high-altitude region, runners coming from lower ground will benefit from a few days of acclimatization and from easing off their usual paces.
